Reaction Conditions

Reaction Steps

To a degassed mixture of ethanol and water (4:1, 20 mL) was added 2-methoxypyrimidin-5-ylboronic acid (0.67 g, 4.4 mmol), Na2CO3 (1.24 g, 11.7 mmol) and N-[2-(4-bromophenyl)ethyl]-4,14-dihydroxy-17-methyl-6-oxomorphinan-3-carboxamide (2) (1.5 g, 2.9 mmol). The reaction mixture was further degassed and then Pd(PPh3)4 (0.32 g, 0.3 mmol) added. The reaction mixture was heated in a microwave reactor at 120° C. for 25 min. and cooled. The reaction mixture was diluted with ethyl acetate (50 mL) and washed with 1:1 brine/water (3×35 mL). The organic phase was dried over MgSO4, filtered and evaporated. The resulting residue was further purified on silica eluting with dichloromethane/methanol (9:1) to give 4,14-dihydroxy-N-{2-[4-(2-methoxypyrimidin-5-yl)phenyl]ethyl}-17-methyl-6-oxomorphinan-3-carboxamide (3) (0.50 g, 32%) as a yellow foam.
